Mid layer thermal Factor 2 balaclava by Sub Zero are manufactured from the same fabric as Factor 2 thermal mid layers. The soft fleeced inner face will keep your head very warm and the hydrophillic treatment will keep a warm dry layer next to your skin without causing irritation.

The Factor 2 fabric is about double the thickness of the Factor 1 but it is still thin enough to be used under a helmet or hard hat.

Ideal for Motorcycles and Mountaineering or part of your winter thermal base layer.
